These are utility functions for adding, removing and combining marks and properties in and slots. ADDMARK and ADDPROP insert a mark or property (a symbol or list of symbols and arguments values) in the appropriate slot of the object. GETMARK and GETPROP find a mark or property given an identifier. The identifier is a symbol or list specifying the mark/property symbol and any number of the arguments following it. The function returns the first mark that matches the specified symbols/values up to the number of symbols/values given. (For example, '(:STARTSLUR- 2) will return the starting mark for a "level 2" slur.) GETMARKS and GETPROPS return all matching marks/properties. RMMARK and RMPROP remove (as a side-effect) all matching marks/properties from the objects. COMBMARKS and COMBPROPS returns a new mark/property list that is a combination of all marks/properties objects in the supplied list (with duplicates removed).
